* Add support to use bash in host resource Netcat's presence is widely regarded as a security issue, and thus not always available. This solution first tries to use bash builtins and timeout (from coreutils), so is less likely to require installing additional packages. * Darwin UDP support in host resource * Host: use netcat first if available Signed-off-by: João Vale <jpvale@gmail.com>
